Group chat improvements.Save chats to your contact list, automatically join selected chats, stay in chat rooms even when closing the window, edit topics directly from the chat window, and much more!

Trillian group chats.In addition to beefing up group chats across the board, we’re also unveiling Trillian group chats in 5.3! Right now you’ll need to be on the beta to take advantage of group chats but we’ll be rolling support out for other devices soon. Trillian group chats are a great way to keep a team connected – they’re persistent and cloud-history backed, ensuring you can catch up on conversation that happened while you weren’t around.

In-game chat.Just in time for Mists of Pandaria, the new in-game plugin exposes an overlay that works inside of full screen games to keep you connected while you play! In-game chat supports tabbed chatting, alerts, and a cool “unread badge” that sticks around even when the overlay isn’t visible so you always know how many unread messages await you. To try it out, simply load a full screen game while the plugin is running and wait for the welcome alert.

SSL improvements.5.3 vastly improves the way Trillian handles SSL certificate validation. The list of root certificate authorities that Trillian trusts is now bundled in a user-configurable text file, and when talking to servers with self-signed or otherwise invalid certificates Trillian will now let you know so that you can decide how to proceed. We also upgraded the version of OpenSSL our clients and servers use, exposing support for ECDHE-RSA-AES256-GCM-SHA384 and forward secrecy when available.

The small stuff.Lots of minor visual cleanups went into 5.3 as well, including some new status icons to make it more obvious who is online and who is away. Both message windows and the contact list have received some shiny new visual upgrades and general cleanups, our Skype integration should now work correctly on Windows 8, and Trillian users can now be invited to Google Talk chat rooms. We also spent some time improving the IRC engine in minor ways for 5.3.
